This member is added by an implicit conversion from Headers to
CollectionsHaveToParArray[Headers, T] performed by method CollectionsHaveToParArray in scala.collection.parallel.
This conversion will take place only if an implicit value of type (Headers) ⇒ GenTraversableOnce[T] is in scope.

Deprecated Value Members

(Since version 0.16.0-RC1) Use response.cookies instead. Set-Cookie is unique among HTTP headers in that it can be repeated but can't be joined by a ','. This will return only the first Set-Cookie header. response.cookies will return the complete list.
